WELLSIN KING APPARATUS.

-1 4 @i 3. ,ilu ii To all iii/1.0m it may concern:

ltnownihat I, li'iA'rrnnw TfCuAr- 311a, a citizen of the United States, residing at Aurora. in the county of Kane and State of lllinois, have invented certain new and useful lmprm'ements in Well-.iinkine, Apimratus, of which the following is a speciiication, reference being had to the accoun panying drawings.

This im'ention-relates to well sinking apparatus and it has for its object the provision oi new and improved means for inserting into the well or taking out of the well the pipes used for boring purposes.

As is well understood in the art, the borin; pipes are used in lengths of about twenty feet ordinarily joined together by screwthreadcd couplings. It is sometimes necessary to remove the boring pipe from the well quite frequently, and it is therefore nccessary that eilieient means he provided for the withdrawal and replacing oi said pipes.

To this end my invention has for one of its speeiiie objects the provision of an improved elevator, as the device is known in the art, by which the lower section of pipe is held against rotation as the upper section is screwed out oi. the coupling when removing the boring pipe'from the well. The means by which I have accomplished these objects are illustrated in the drawings and are hereinafter specifically described.

That which I believe to benew is set forth in the claims.

in the drawings,i igure 1 is a central vertical section through theupper portion of the well pit and the apparatus mounted at that point; Fig. 2 is a horizontal section taken substantially on line 2-2 of Fig. 1; Fig. 3 a horizontal section taken substan tially on line 33 of Fig. 1; Fig. 4; is a vertical section taken substantially on line 4-l of Fig. 3; Fig. 5 is a view from the right of the part shown in Fig. 4.

Referring to the several figures of the drawings in which correspondlng parts are indicated by the same reference characters,-l5 indicates a frame located at the upper end oi the well pit 16 and having mounted thereon a bed-plate 17, rising from which is an. annular sleeve 18.

it) indicates a series of anti-friction rollers mounted in a suitable annular channel in the hail-plate 17, being adapted, to run therein upon a hardened ring 20.

47 indicates a clip pivotany mounted in the free end of the. member 35 and adapted to be turned up over the free end of the member 36 so as to hold said two members in position about a pipe.

48-49 indicate laterally extending lugs upon the members l53ll, respectively, the ends of which lugs are turned upinto vertical position tribe-engaged by a suitable As best shown in Fig. 3, the clip 4? when turned into locking: position extends clear to the pipe 39 clamped by the elevator.

5()5l indicate oppositely-disposed lugs at one side of the opening through till coverplate 33, and 3253 indicate similar lugs at the opposite side of said opening. As best shown in Fig. 5, the adjacent faces of said lugs are beveled and of such a distance apart as to receive the elevator 35-436 in closed position between them.

5455 indicate buttons extending from the members 35-3tl for the insertion of links for raising the elevator, as will be readily understood.

It will be understood that in practice two elevators such as that just described will be used, one in the position shown in Fig. l, and another at the upper end of the pipe section ll ith the pipes 38-1l9 being held in suspension by means of an elevator at the upper end ofthe pipe 38, the mode of applying the elevator shown will be as follows: The pipe sections 38-39 would first be raised above the position shown in Fig. 1, whereupon the two members 35-36 of the elevator would be placed in position about the pipe section 39. The clip 4? would then be turned into the position shown in Fig. 4 with its inner end against the pipe 39 and with the lugs 48-49 of the said two members extending through the o ening in said clip 47. The elevator woul then be raised u on the ipe section 39 until the inner en of the clip 47 was brought against the lower edge of the coupling 40, whereupon the two sections of pipe 38--39 with the elevator in position thereon would be lowered until the elevator was brought into engagement with the cover-date 33 between the lugs 56-51 at one side and the lugs 5253 at the other side. The screws 44 woulgl then be tightened bringin the inner ends of the blochs {i1 into forci le contact with the coupling 40 below the central horizontal line oi saidcoupiing, as shown in Fig. 1. The clamp members 3 536 would then be held in loc red relation to each other not only by'the clip 47 but also by the diagonally-positioned lugs 5-0-51-52-53 at op- :in this way the Weight of the line of boring pipes isposite sides of said two members.

brought into play to hold the elevator secing and supporting of the boring pipes.

it reason of the engagement of the blocks ll upon the coupling 40 at or below its central horizcmtal plane only, the clamping force of the elevator is prevented from causm an undue springing of the sides of the pipe section 38 toward each other whereby it would be difficult to unscrew the section 38 from the coupling 40.

Coming now to a description of the means by which the upper section of pipe is turned in either direction as desired when the lower section is being held against rotation by the elevator 35-36, 56-57 indicate sockets pivotally mounted upon the posts 28-29, re

spectively, being held in position thereon by suitable collars 58. 59-60 indicate blocks of rubber mounted in the sockets 56-5'? be ing provided with suitable openings for the insertion of wrench handles til-2, respectively. (33 indicates a clamp member pi? otally connected with the handle 51. and 6%;

indicates a clamp member pivotaliy conneeted with the clamp member 83. 65-35 motto cate clamp members similarly connected together and connected with the handle 32. As best shown in Fig. '2, each oi the clamp members 63646566 is provided upon its inner face with suitable teeth by which it is adapted to bite into a pipe upon whiclrit is tightened. As best shown in Fig. 2, the handle 61 is provided with a curved arm 67 which is adapted to engage a suitable hook 8 in the end of th" clamp member 59 indicates a curved itrm extending from the handle 62 adapted to engage a hoolr' in formed in the end of, the clamp member 6st. As will be readily understood, with the tongs orv wrench applied to the pipe 38, as shown in Fig. 2. if the handles ill- 6? be turned in counter-clockwisedirection in said figure he clamp members 63-i34-3566 will'be tightened upon the pipe and a tur' vupon. their pivotal connections with the clamp members, freeing the arms 61 -439 from the hooks i38-?0, respectively. and releasing the Wrench entirely from the pipe. if it were desired to turn the pipe 38 in clockwise direction. this could be accom plished by the application the Wrench in inverted position, as will be readily,under-- stood. When the Wrench members have been freed from engagement withthepipe it is apparent that they may be pushed back out of the way by reason of the resiliency of the parts 59-450, in which position they will be ready for use at a later time without the necessity for lifting them again into p sition. It will be understood that as the pipe 381is screwed out of the coupling 40 the pipe will be raised relative tothe sockets 5657 by a distance approximately equal to one-half the length of the couplings 40, thus bringing the inner ends of the handles 6152 by such a distance higher than their outer ends. This is made practical by the use of the resilient blocks 5960.

By the use of my improved form of wrench the possible slipping of the wrench upon the pipe is prevented from causing any damage. As willbe readily understood, when two separate wrenches are used one connected with the standard at one side of the rotary and the other connected with the standard at the other side of the rotary,

when one wrench slips the rotation continues through the medium of the other wrench alone. for rotating the pipe at one side is likely to force the pipe to one side and in some cases even causes a breakage ot the pipe;

In the use of my improved wrench, when one of the chains of clamping blocks slips the other chain of clamping blocks is also-loosened upon the pipe and the driving ceases entirely until both chains again simultaneously grip the pipe.

Inasmuch as the gripping blocks carried by the elevator members are of-a greater radial length about their pivot points at the side edges than at the central point, it is evident that as said gripping blocks are turned on their pivots the gripping blocks are caused to bite into the pipe and to hold it very firmly against rotation.

In the use of my improved construction for boring purposes, the wrench above de scribed is applied to the boring pipe just as it would be for screwing the sections of the boring pipe together. When the pipe tremblcs or jumps as it does in the operation of boring, the wrench is adapted to slip longitudinally of the boring pipe which follows up the advance of the drill, by'reason of the jar upon the wrench and by reason of the fact that the gripping teeth of the wrench are vertically disposed, but the wrench is held normally against turning relative to the boring pipe. The elevator in.

not used during the boring operation, adjacent to the cover-plate and the wrench may rest upon the cover-plate or may be mounted higher on the posts 28-129 as desired according to the requirements in the process of boring.

: vice The application of power.

While I have shown the part 33, by which the elevator 3536 is supported and held against rotation, in the form of a coverplate it will be understood that I do not restrict myself to that particular form of deexcept as hereinafter specifically claimed, inasmuch as any suitable means to this end may be used.

While I prefer to use the form of wrench shown in the drawings comprising handles 61-452 suitably mounted uppn the rotary, I do not restrict myself to that particular form of-wrench, except as hereinafter specifically claimed, the essential point being that the gripping means of the wrench is caused to rotatenvith the rotary and to turn the pipe with it.
